Some foks use electric sanders for tillerin'. You have ta be really experienced and even then EXTREMELY careful. You can tiller with a rasp, course then fine er a sharp scraper and sandpaper, er any combination of these er other hand tools. It will give ya a slow look at whats happenin' ta the wood. Speed is not important here. One mistake with a power tool (electric sander) and yer in a world of trouble with the bow wood ( hinges,etc.) So, after long winded answer Imo no, its not a good idea ta tiller with a electric sander...........................bob
